      I have been commissioned to do 2 Baldwin Sharks from Facebook, I figured the one that I scratch built a few years ago is lonely I can do 1 for me as well


      I started  with a reference drawing, the guys measurements aren't 100% compared to the D&H unit i'm modeling but I can correct those issues later

       

       


      and here is the 3d model that's being extruded from that drawwing

       

      I should be able to start printing parts by the end of next week if all goes as planned


      The frame will use the aristo f unit, along with the motor blocks, the fuel tank will be swapped out as well


      I will eventually offer the shell of the Shark for a reasonable price here...

      Cool, I'm just thinking of all the stuff that can be made using the printers and available chassis. Like a DL109 shell over an E8 chassis or a Raymond Lowie streamline locomotive shell over an old Pacific or Bug Hauler chassis.

      Mark , 

              Not having had first hand experience of 3D stuff , how does its strength compare to a similar sized plastic moulded body ? 

       Obviously , reinforcing would be simple enough , so don't think this is an implied criticism ; far from it , anything that helps the hobby and makes more obscure bits available is to be highly commended . Not that the Shark Nose is obscure , even I know about them (got them in H0).

       I would be interested to see your finished product , and I am sure that others here would be too .

       Keep up the good work , we need adventurous people like yourself to advance things .

      The walls of this will be almost double the size of the gp30-c that I did, and that extra thickness is "for good measure" I'm comfortable with half the thickness for myself. the Alco long high hood I did last week is brick strong, i'm betting that I could stand on it without crushing it

      I did a paper model warehouse back 10 years or so ago in HO scale, yeah you could stand on it. It's not that difficult to do

      Gee, and I have an Aristo FA1 that I just don't know what to do with. A PRR Shark would be just too cool.

      Will you be making B units to go with the A unit?
      I am looking forward to seeing the finished model.

      Mark, the National PRR Technical & Historical Society has drawing for the Shark available.  Probably spendy, but at least you will get it right.

      I have been trying to draw the shark in SolidWorks but the nose is slowing me too. When I found this thread I put it on the back burner. Now I thought about putting my efforts into a cabin car.

      Your work has inspired me to get my 3d printer going again.

      this is where I started from, converting those angles of the nose are a bitch to say the least

      What this Steve?

       

      No, Mark, that is the free drawing, and it is worth every penny that you paid for it.  I said they would be spendy, and I meant it.  It will be on one of their CD's, contact the Society.  Of course, you could just continue to wing it...

      Yes I will do a b unit, just won't be doing one in D&H colors as they never had the B unit



      because of its simplicity it may be done before that damn nose on the A unit, lol, man that ones driving me nuts trying to draw in 3d AND make it printable...

       

      So, a B unit would be cheaper? :-)
